Abstract:
An excavating bucket includes a bottom surface section, a bucket body having a rear surface section and a side surface section, a lip section, a bracket, and teeth. The lip section is fixed to an edge portion of the bucket body at an opposite side to the rear surface section. The bracket has a hole through which a coupling pin for attaching to the arm passes. When the length of a virtual line S1 linking the center of the hole and the front end of the lip section is set as a wrist radius V, a length of the longest line segment perpendicular to the virtual line S1 from the virtual line S1 to the bottom surface section is set as a bucket depth D, and the angle formed between the lip section and the virtual line S1 is set as a lip angle θ, 62°≦θ≦72° and 0.7≦D/V≦0.8.
